What Home Addition Work Covers
Room additions are a broad category that span everything from constructing a new bathroom to major kitchen expansions. At their heart, room additions involve expanding your home's existing structure — either upward. This is not the same as remodeling, which reconfigures the current square footage.
These builds require a collaborative approach that involves architectural planning, building permits, foundation work, rough construction, electrical, plumbing, insulation, interior finishing, and flooring and trim. Because room additions touch so many systems, choosing a general contractor who can coordinate each phase is essential.
Room additions are commonly chosen by homeowners who have outgrown their current layout but aren't ready to move. They're frequently selected for homeowners planning to age in place. Regardless of the scope, the approach follows a structured set of phases that our team have mastered through experience.
